1.25" Twist Lock Adapter for 2" SCT Threads, for C5, C6 and
Other Small SCTs, Meade ETX Models and Orion/SW MAKs.
This 1.25" adapter locks with a twist, holding 1.25" eyepieces and
accessories securely, very well centered and aligned. The 0.6" wide
compression band solves problems caused by safety recesses found
on some eyepieces and accessories.
For smaller scopes that have small optical paths and don't benefit
from larger adapters, this is a low profile and high quality visual
back for attaching eyepieces, diagonals, cameras and other goodies.
Fits the back of SCTs that have male 2" diameter threads.
Removing the twist ring exposes male T-threads, so these adapters
double as a sturdy T-thread adapter.
CNC machined anodized aluminum body and lock ring, graphite-nylon
compression ring. Weighs 4.5 oz. Low cholesterol, no GMOs. With
